As a grounding stone, black tourmaline can be used whenever energy feels scattered and disconnected. It therefore, brings awareness back to a grounded state of mind. Tourmaline does not absorb negative energy. It repels it. It is the best crystal to use against the ill effects of low frequency and high frequency electromagnetic waves (EMF) and protects against psychic attacks and repels all kinds of negative energy. It grounds energy as it is connected to the Root/Base Chakra. When the tourmaline is rubbed it becomes charged with magnetic electricity. It is suggested to carry this stone when you feel surrounded by negativity. (Source: peacefulmind.com)

Black Tourmaline is a premier stone of the ages. It has the ability to transmute and purify negative energy and turning it into usable energy. Makes a great decorative peace in the office, home or anywhere there is conflict and a need for clearing.

Black Tourmaline is a powerful protective stone.
Black Tourmaline keeps an electric charge, as it is pyroelectric (meaning it can generate electricity when heated), as well as piezoelectric (meaning it can store an electrical charge), causing it to release negative ions and far infrared radiation - these are very beneficial for health. This incredible stone is associated with protection, grounding, health, happiness, luck, and positivity.
